2025-05-27	_README.txt				M. Wiget	This file

2025-04-25	instrument-preferences_data-analysis.R	M. Wiget	R-script for the data analysis in the paper; it contains(1) the Bayesian ordinal regression
									models to test the relationship between actors' instrument preferences and the relative 
        								importance of core beliefs about achieving health, environmental, agro-economic, or socio-
									political objectives or their risk attitudes in achieving these objectives (including 
									corresponding outputs: Figures 2�4, Figure A-2, Table A-2) and (2) the visualization of 
									the variance in the importance of policy core beliefs (Figure A-1).    

2025-04-25	instrument-preferences_model-data.csv	M. Wiget	Data for the Bayesian ordinal regression models; cleaned and anonymized data from an
									online survey among 54 key actors in Swiss pesticide risk reduction policy (response 
									rate ~ 85%; N = 46) and a focus group workshop with a sub-sample of 24 representative 
									actors policy, held in Bern on June 1, 2023. The file contains (1) the actors' (rows) 
									level of support (1 ~ "no support at all" to 5 "fully supported") for particular policy 
									instruments (R ~ repressive/regulatory, C ~stimulative/regulatory,T ~ repressive/market-
									based, M ~ stimulative/market-based, P ~ persuasive instruments);(2) the weights of the 
									the most variable objectives (Var1_) in the domains of human health, environmental 
									protection, agro-economic productivity, and socio-political costs; and (3) the risk 
									attitudes in achieving the objectives in each domain (RA_). The file also contains data 
									on the control variables; actor type (AD ~ administrative actors, SC ~ scientific actors, 
									IG ~ interest groups) and the collaboration partner support index (CPSI).  
										
2025-04-25	instrument-preferences_weight-data.csv	M. Wiget	Data to visualize the variance in the importance of policy core beliefs; cleaned
									and anonymized data collected in a focus group workshop with 24 representative actors
									of Swiss pesticide risk reduction policy, held in Bern on June 1, 2023. The file  
									contains the weights assigned by the workshop participants (rows) to 16 health, 
									environmental, agro-economic, and socio-political objectives (columns). The weights
									were calculated using the rank sum approach. For this, the actors had to rank the 
									objectives in order of importance for achieving them.
